Chinese public institutions bring you the basic knowledge of China's ancient mathematical achievements, hoping to help candidates prepare for the examinations of public institutions smoothly.
Parallel Computation Classics of the Zhou Dynasty is China's earliest work on astronomy and mathematics. It was written in 1 century BC and recorded a conversation between Shang Gao and Zhou Gong. Shang Gao said, "Therefore, it was broken, with three changes in shares, four changes in shares, and five changes." That is, when two right-angled sides of a right-angled triangle are 3 (short side) and 4 (long side) respectively, the radius angle (chord) is 5. Later generations simply described this fact as three strands, four strings and five hooks. Because the content of Pythagorean theorem was first seen in the text of quotient height, people call this theorem "quotient height theorem".
The Analects of Confucius and The Classic of the Rubik's Cube in the Spring and Autumn Period are the earliest magic records in China, while in foreign countries, the Rubik's Cube appeared in the 2nd century, more than 600 years before China. Rubik's cube, also known as Rubik's cube and phalanx, originated in China. Yang Hui, a mathematician in the Song Dynasty, called it a vertical and horizontal map.
Nine Chapters Arithmetic, written around 1 century, is the most important and far-reaching mathematical work in China. Many people in later generations, such as Liu Hui and Zu Chongzhi, commented on Nine Chapters Arithmetic. Liu Hui, in particular, added a lot of his own opinions and expounded important mathematical theories.
Fractional arithmetic and decimal. China's complete fractional arithmetic appeared in Nine Chapters of Arithmetic, and the same law appeared in India in the 7th century. China is more than 500 years earlier than Indian.
Zu Chongzhi was born in a calendar family. He is one of the few mathematicians who can be listed in the official history. Zu Chongzhi's greatest mathematical achievement is the accurate calculation of pi. Zu Chongzhi is ahead of the west in the calculation of pi for nearly a thousand years. To commemorate Zu Chongzhi's contribution, Japanese astronomers in the 20th century named a planet they discovered after Zu Chongzhi.
For the need of official mathematics education, Tang Gaozong personally ordered to sort out previous mathematics works. In 656 AD, Li was in charge of compiling ten ancient books on calculation: Zhou Pi's Love Calculation, Nine Chapters of Arithmetic, Sun Tzu's Arithmetic, Wu Cao's Arithmetic, Zhang Qiu's Arithmetic, Xiahou Yang's Arithmetic, Ji Gu's Arithmetic, Island Arithmetic, and Zhangfa.
Qin, Yang Hui, Li Zhi and Zhu Shijie were outstanding mathematicians in the Song and Yuan Dynasties, and they were called "four great masters in the Song and Yuan Dynasties". The representative works of mathematics in Song and Yuan Dynasties include "Counting Books and Nine Chapters" and "Detailed Explanation of Nine Chapters Algorithm".
Minggatu, a Mongolian mathematician in Qing Dynasty, introduced the "Nine Methods of Tangential Circle".
China's earliest mathematical works are:
A. Zhou Bi suan Jing
B. "Writing"
C. "Nine Chapters of Arithmetic"
D. Shu Shu JIU Zhang
Answer A. Analysis: The Weekly Parallel Computing Classic is the oldest astronomy and mathematics work in China, which was written in BC 1 century. The main achievement in mathematics is the introduction of Pythagorean theorem. So the answer to this question is a.
Methods Summarize that in recent years, the common sense of literature and history accounts for a large proportion in the examinations of various institutions in Shanxi, mainly by rote, so we should pay attention to accumulation, remember more and do more.
